RAIL ANCHOR TIE PLATE.

Ap lication filed January 12, 1924. Serial No. 685,754.

T all whom it may concern:

Be it known that I, PERRY H. HAMILTON,

a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Rail Anchor Tie Plates, of which the following is a specification. 7

My invention relates to rail anchor tie plates and it is the principal object of my invention to provide a new and improved form of tie plate differing only slightly from the ordinary tie plate for causing it to grip the rail as a combination tie plate and rail anchor. I

It is one of theparticular objects of my invention to improve devices of this type in such a manner as to reduce very materially the cost of the anchorage effected as compared with the cost in cases where separately i formed devices are employed independently of the tie plates.

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. means by which I have accomplished my several objects are illustrated in the accompanying drawing and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawing-- Fig. 1 is a vertical cross section through one of my improved tie plates in operative positionv between the rail and the cross tie, the head portion of the rail being broken away.

Fig. 2 is a fragmentary view similar to a portion of Fig. 1, but showing a changed position of the snap dog. I

Fig. 3 is a perspective view of the snap dog; and

Fig. 4 is a top plan view of the parts shown .inl ig. 1.

Referring to the several figures of the drawing, in which corresponding parts are indicated by the same reference characters,

10 indicates the base portion of a railroad rail, comprising a horizontally extending flange at each side of the web 11. The rail 10 is mounted upon a cross tie 12, with a tie plate 13 interposed between the rail and the tie. The tie plate 13 is provided with one or more lugs 1 1 on its lower face adapted by engagement with the cross tie 12 to hold the The preferred plate against movement upon the upper face of the tie, the plate 13 being secured in position upon the tie by a plurality of spikes 15. Near one end of the plate 13, theplate is provided upon its upper face with a aw 16, in the construction shown the 16 being formed integrally with the plate 13. The jaw 16 as shown comprises a rib extending the full width of the plate 13, such rib being undercut so as to receive between it and the adjacent portion of the body of the plate the flange of the rail base 10, as shown in Fig.1, the space between the overhanging rib 16 and the body of the plate 13 being such that the parts have a driving fit.

At its opposite end, the 'plate 13 is connected to the flange of the rail base by means of a jaw having removable engagement with the flange, such jaw being 'in the form of a dog 17. In the construction shown the dog 17 is formed separately from the plate 13, being applied to the plate by insertion through an opening 18 in the plate 13. ;As isbest shown in Fig. 1, the lower end of the dog 17 comprises a hook portion 19 Which engages the adjacent lug 14 within a small recess 20 cut in the upper face of the tie 12. In'Fig. 2, the dog 17 is shown in its position just after being engaged with the lug 1 1 of the plate 13, and just ready for engagement of the jaw 21 with the upper face of the adjacent flange of the rail base,- the jaw 21 being formed on the upper end of the dog 17 in such spaced relation with re spect to the hook 19 that when the dog is driven into the operative position, as shown in Fig. 1, the jaw 21 grips the flange very firmly for preventing the rail from slipping longitudinally with respect to the plate 13. In the application of the device to a rail, after the dog 17 is driven to the position shown in Fig. 1, a spike 15 is inserted through the opening 18, serving both to connect the plate 13 to the tie 12 and also to prevent the dog 17 from loosening upon the flange of the rail base 10.

In the construction shown in Fig. 4, two of the dogs 17 are employed in connection with a single plate 13, and that is the construction'which I prefer to employ. It will be understood, however, that I do not desire to limit myself to the use of any particular number of such dogs, except in so far as the claims may specify a particular number of such dogs.

It will be understood further that I do not desire to limit myself to the use of the details of construction as illustrated in any particular, except so far as such detailed construction is specifically claimed, inasmuch as it is evident that various changes might be made in the construction and arrangement without departing from the spirit of my invention.

I claim:

1. In combination, a. plate for supporting a railroad rail on a cross tie, a lug on the lower face of the plate adapted by engagcment with the tie to hold the plate in posi tion thereon, a jaw carried by the plate adapted to grip the base flange at one side of the rail, and a second jaw comprising a separately formed dog adapted at its lower end to engage said lug and at its upper end to engage the upper face of the flange of the rail for securing the plate to the'rail.

2. In combination, a- ;plate for supporting a railroad frail on a cross tie, a lug .on the lower face of the plate adapted by engagement with the tie to hold the plate in :position thereon, a jaw carried by the plate adapted to grip the base flange at one side of the rail, and a second jaw comprising a separately for-med dog extending through an opening in said plate into engagement at its lower end with said lug and engaging at its upper end with the upper face of the flange ofthe rail for securing the plate to the rail.
